The King's African Rifles (KAR) was a multi-battalionBritish colonial regiment raised from Britain's various possessions in East Africa from 1902 until independence in the 1960s. It performed both military and internal security functions within the colonial territory, and served outside these territories during the World Wars. The rank and file (askaris) were drawn from native inhabitants, while most of the officers were seconded from the British Army. When the KAR was first raised there were some Sudanese officers in the battalions raised in Uganda, and native officers were commissioned towards the end of British colonial rule.

Until independence, the parade uniform of the KAR comprised khakidrill, with tall fezes and cummerbunds. Both items were normally red, although there were some battalion distinctions with Nyasaland units, for example, wearing black fezes.

Prior to 1914, the regiment's field service uniforms consisted of a dark blue jersey and puttees, khaki shorts and a khaki fez cover with integral foldable cloth peak and neck flap. Askaris wore sandals or were barefoot, on the rationale that the heavy military boots of the period were unsuitable for African recruits who had not previously worn footwear.[1] Fezzes bore an Arabic or Roman number with the wartime-raised battalions wearing theirs on geometric-shaped patches of cloth. During the Great War, all the dark blue items were replaced with khaki equivalents, and a short pillbox hat with a khaki cover was worn on campaign. After the war, the khaki shirt was replaced by a collarless blue-grey angora shirt called a "greyback".

The King's African Rifles took part in the campaigns against Mohammed Abdullah Hassan in Somalia during the early 1900s. Hassan was known to the British as the "Mad Mullah". The KAR were part of the British air and ground force that defeated Hassan in 1920.

The KAR began the First World War with 21 small companies in three battalions (each with up to eight companies following the British pre-1913 half-company establishment): the 1st Nyasaland (half of the battalion was located in northeast Nyasaland), 3rd East Africa (with one company on Zanzibar) and the 4th Uganda, both of the latter included a 4th platoon of Sudanese with the 4th platoons of 4th battalion being led by Sudanese officers. Additionally the companies were scattered over British East Africa.

Full strength of the KAR in 1914 was 70 British officers, three British NCOs, and 2,325 Africans. There were no organic heavy weapons (each company had only one machine gun), including artillery or organised reserves and the companies were in reality large platoons of 70 to 80 men.

In 1915 the KAR was expanded by having the three battalions reorganised into standard four-company battalions, which were then brought up to full strength at 1,045 men each. It was not until early 1916 that the 2nd Nyasaland and 5th Kenya battalions [1916–1963] were re-raised, this being due to do with white sensitivities in Kenya about arming and training large numbers of black African troops. Later in 1916 the 2nd, 3rd and 4th battalions were expanded into two battalions each through recruiting in their home areas. It was not until General Hoskins (formerly the Inspector General of the KAR) was appointed to command British East African forces in 1917 that genuine expansion began. The 1st Battalion was doubled and the 6th (Tanganyika Territory) Battalion was raised from Schutztruppe of the former German East Africa and then it too was doubled. The 7th was formed from the Zanzibar Armed Constabulary and the Mafia Constabulary. Later in 1917 many other duplicate battalions were created as the first four battalions (now called regiments in the British tradition) each raised a 3rd battalion and a 4th or Training Battalion. The 4th Regiment raised an additional two battalions, the 5th and 6th through recruiting in Uganda. The KAR Mounted Infantry Unit (on camels), originally part of the 3rd regiment and the KAR Signals Company were also raised.

By the end of the Great War the KAR comprised 1,193 British officers, 1,497 British NCOs and 30,658 Africans (33,348 total) in 22 battalions, including two made up of former German askaris, as noted above. In Armies in East Africa 1914–18, Peter Abbot notes that the KAR units recruited from former prisoners of war were used as garrison troops by the British, to avoid any conflict of loyalties. However, one of these battalions was involved in the pursuit of a force under Hauptman Wintgens from February to October 1917.

KAR casualties in the First World War were 5,117 killed and wounded with another 3,039 dying from diseases.

During the interwar period, the KAR was slowly demobilised to a peacetime establishment of six battalions, at which strength the regiment remained until the Second World War. In 1938, the regiment was composed of two brigade-strength units organised as a "Northern Brigade" and a "Southern Brigade." The combined strength of both units amounted to 94 officers, 60 non-commissioned officers, and 2,821 African other ranks. After the outbreak of war, these units provided the trained nucleus for the rapid expansion of the KAR. By March 1940, the strength of the KAR had reached 883 officers, 1,374 non-commissioned officers, and 20,026 African other ranks.[2]

Initially the KAR was deployed as the 1st East African Infantry Brigade and the 2nd East African Infantry Brigade. The first brigade was responsible for coastal defence and the second for the defence of the interior. (See 1st SA Infantry Division). By the end of July 1940, two additional East African brigades were formed, the 3rd East African Infantry Brigade and the 6th East African Infantry Brigade. Initially a Coastal Division and a Northern Frontier District Division were planned, but, instead, the 11th African Division and the 12th African Division were formed.

The two divisions included East African, Ghanaian, Nigerian, and South African troops. The Ghanaian and Nigerian troops came from the Royal West African Frontier Force. Under the terms of a war contingency plan, a brigade each was provided from the Gold Coast (now Ghana) and from Nigeria for service in Kenya. A Nigerian brigade, together with two East African brigades (the KAR brigades) and some South Africans, formed the 11th African Division. The 12th African Division was similarly formed, but with the Ghanaian brigade instead of the Nigerian brigade.

The 11th African Division was disbanded in November 1941 and the 12th African Division was disbanded in April 1943. In 1943, the 11th (East Africa) Division was formed and it fought in Burma. In addition, two independent infantry brigades were sent from East Africa to India for service in Burma. The 22 (East Africa) Infantry Brigade served in the Arakan under command of XV Indian Corps, while the 28th (East Africa) Infantry Brigade served under IV Corps, playing a crucial role in the crossing of the Irrawaddy River.

By the end of the war the regiment had raised forty-three battalions (including two in British Somaliland), nine independent garrison companies, an armoured car regiment, an artillery unit, as well as engineer, signal and transport sections.

The regiment played a major role in operations during the Mau Mau Uprising in Kenya. In 1952, the 7th (Kenya) Battalion was reformed; it was renumbered as the 11th (Kenya) Battalion in 1956. 2nd/3rd Battalion, a reserve unit, was raised during the military phase of the emergency in Kenya and was under consideration for disbandment by 1957.[4]

The 1st, 2nd and 3rd battalions saw service in the Malayan Emergency, where they were heavily involved in fighting Communist rebels, suffering 23 dead.

The extent to which KAR traditions influence the modern national armies of the former East African colonies varies from country to country. In Tanzania, a mutiny in 1964 led to a conscious decision to move away from the British military model. In Kenya, on the other hand, the title of Kenya Rifles survives and the various campaigns in which the KAR distinguished itself in both World Wars are still commemorated.

The regiment's battalions were not awarded colours until 1924, as colours were not traditionally carried by rifle regiments. The colours had many of the regiment's battle honours emblazoned on it. The old colours were replaced in the 1950s.
